Automatic irrigation with solar tracking system

The Automatic Irrigation with Solar Tracking System integrates the renewable application of solar energy with automation to address the agricultural problems and challenges such as inefficient irrigation system, energy scarcity and inefficiency of water distribution to the crops. By using an Arduino UNO R3 microcontroller, the system processes data from the soil moisture sensors, DHT11 temperature sensor and photoresistors to optimize water distribution and increase the maximum solar energy intake. The single-axis solar tracker which tracks the movement of the sun according to the light intensity ensures solar energy capture with the addition of a 5V relay that acts as an automatic switch to the DC water pump for precise irrigation. This project also includes a real-time monitoring display through the LCD I2C display module. This displays real-time data of the moisture level percentage in the soil and the surrounding temperature during usage. This innovative, eco-friendly solution boosts agricultural productivity, conserves resources and operates effectively in off-grid areas, making this a valuable tool for sustainable agriculture.
